2.6 Minimize EditText height Based on Reflection library.

2.7 Changing color of selected text in a Label

Sub Activity_Create(FirstTime As Boolean) Dim l As Label l.Initialize("l") Activity.AddView(l, 0, 0, 100dip, 100dip) l.Text = "Some text" SetColorList(l, Colors.Yellow, Colors.Blue) End Sub Sub l_Click End Sub Sub SetColorList (Label1 As Label, DefaultColor As Int,PressedColor As Int) Dim sd As StateListDrawable Dim clrs(2) As Int Dim states(2,1) As Int clrs(0) = DefaultColor clrs(1) = PressedColor


states(0, 0) = sd.State_Pressed Dim r As Reflector Dim csl As Object csl = r.CreateObject2("android.content.res.ColorStateList", _ Array As Object(states, clrs), Array As String("[[I", "[I")) r.Target = Label1 r.RunMethod4("setTextColor", Array As Object(csl), _ Array As String("android.content.res.ColorStateList")) End Sub

2.8 SelectionEnd in an EditText Based on Reflection library.

Sub GetSelectionEnd(txt As EditText) As Int Dim r As Reflector r.Target = txt Return r.RunMethod("getSelectionEnd") End Sub

2.10 SQLite BLOB UPDATE SQL1.ExecNonQuery2("INSERT INTO table2 VALUES('smiley', ?)", Array As Object(Buffer))

2.11 Rename a folder Sub Activity_Create(FirstTime As Boolean) RenameFolder(File.DirRootExternal, "test1", "test2") End Sub Sub RenameFolder(Parent As String, CurrentFolder As String, NewFolder) Dim p As Phone Dim args(2) As String args(0) = File.Combine(Parent, CurrentFolder) args(1) = File.Combine(Parent, NewFolder) p.Shell("mv", args, Null, Null) End Sub

2.12 Webviewscrolling

So, in summary, to scroll a WebView to a particular DOM element, write a JavaScript function to do the scrolling:


function scrollToElement(id) { var elem = document.getElementById(id); var x = 0; var y = 0; while (elem != null) { x += elem.offsetLeft; y += elem.offsetTop; elem = elem.offsetParent; } window.scrollTo(x, y); }

and then from your Android app (Java code), tell your WebView to load a URL:

webView.loadUrl("javascript:scrollToElement('" + elemId + "')");

There are some issues with this approach, such as the scroll will not be nicely animated, but the general mechanism works.

2.13 Change color of Android ProgressBar Based on Reflection library.

Array As Object(r.GetStaticField("android.R$id", "progress"), clipDrawable), _ Array As String("java.lang.int", "android.graphics.drawable.Drawable")) End Sub

2.29 Pseudo Custom Controls Here is a very simplistic implementation: Code module named C1 Sub Process_Globals Type MyView (p As Panel, b1 As Button, l1 As Label) End Sub Sub CreateMyView(ButtonEvent As String, ButtonText As String, LabelText As String) As MyView Dim m As MyView m.Initialize m.p.Initialize("") m.b1.Initialize(ButtonEvent) m.b1.Text = ButtonText m.l1.Initialize("") m.l1.Text = LabelText m.b1.Tag = m 'store the structure in the button's Tags property. m.p.AddView(m.b1, 10dip, 10dip, 100dip, 40dip) m.p.AddView(m.l1, 10dip, 50dip, 100dip, 40dip) Return m End Sub Sub ChangeValue(m As MyView, value As String) m.l1.Text = value End Sub

Activity: Sub Process_Globals End Sub Sub Globals Dim m1, m2 As MyView End Sub Sub Activity_Create(FirstTime As Boolean) m1 = c1.CreateMyView("m1", "Button #1", "Label #1") Activity.AddView(m1.p, 10dip, 10dip, 100dip, 200dip) m2 = c1.CreateMyView("m2", "Button #2", "Label #2") Activity.AddView(m2.p, 10dip, 110dip, 100dip, 200dip) End Sub Sub m1_Click c1.ChangeValue(m1, "new value") End Sub Sub m2_Click c1.ChangeValue(m2, "new value2") End Sub


2.30 Elipsize a Label Needs the reflection library. Sub Activity_Create(FirstTime As Boolean) Activity.LoadLayout(1) Label1.Text = "this is a very long text."
